Definitions
- the invention relates to a torsion damper having an input part which is rotatably connected to a crankshaft, and a hub flange which is coupled to a hub, wherein the input part and the hub flange are coupled via at least one energy storage element such that a torque from the crankshaft via the at least one energy storage element is transferable to the hub.
- Such torsion dampers are known in the art and are used to damp torsional vibrations caused by a discontinuous introduction of force into a shaft. For example, in drives with internal combustion engines, a force is transmitted to the shaft only at the ignition of a cylinder, which causes vibration at a constant speed of the shaft with a fixed frequency. Such torsional vibrations can be reliably damped with the known torsion damper.

- a damping effect can be adjusted by the applied force, for example by selecting the diaphragm spring with a desired spring constant or the adjustment of the bias voltage.
- the plate spring is supported on the hub flange and on the input part is fastened via connecting elements, in particular rivets, a counter-disc such that the counter-disc and the input part are positioned on different sides of the hub flange in the axial direction, wherein the plate spring against rotation is held the connecting elements.
